Product Description
This product is a general-purpose chloroprene rubber synthesized via emulsion polymerization, using sulfur as a regulator and chloroprene and dichloroprene as comonomers. It closely resembles DuPont's GRT-type and Japan Denka's PS-40 chloroprene rubbers.
Product Performance
The crystallization rate is moderately low, with a density of 1.23. It appears as off-white or light brown lumps and exhibits excellent resistance to crystallization, along with excellent moldability and adhesion. This makes it the preferred adhesive type for high-strength, dynamic applications, while also offering superior cold-temperature performance.
Main uses
This product boasts excellent cold resistance and is the preferred rubber type for high-strength, dynamic applications, making it ideal for manufacturing drive belts, synchronous belts, poly-V belts, and more.
